“The government should seize all such houses.”
This should be fun.
Building permits, excessive utility usage, nosy neighbors, maybe even thermal imaging...all “weapons” utilized in the war on drugs...should lead to many busts. With the massive support Trump has for his illegal alien “roundup”, many Americans will be onboard and participating. If I see unfamiliar multi-family faces entering a home in my neighborhood...I’m calling ICE.
And yes...arrest the owners, seize/auction off the houses and deport the illegal aliens.
